Tuning Maestro – On this day in 2007 saw the passing of one of the great Triumph engine mechanics of the sixties. Jack Shemans cut his engineering teeth on Daimler cars and Armstrong-Whitworth aircraft before joining the Meriden factory of Triumph Motorcycles. In the thick of engine development he took the 500cc Tiger engined bike’s to racetrack victories such as Percy Tait’s Works 500GP seen in the posts image. Incidentally this months edition of Motorcycle Classics has a detailed article about this bike. Jack also helped beef up the horsepower of the Triples to get their Daytona successes. From the people who knew him he was a kind, generous and knowledgeable man.
